Facebook: A Timeline

The Enemy of My Enemy

Friendster and MySpace were long ago mowed down, clearing a path for Facebook. Google+ is now its only true competitor, with 90 million users (though that number is in dispute). Microsoft, Google's search rival, paid $240 million for a 1.6 percent share of Facebook in 2007. The bond between the companies goes even deeper, with Microsoft's recent purchase of Facebook partner Skype.
